DUPLEX PEN.

SPECIFICATION forming part of Letters Patent No. 611,050, dated September 20, 1898.

Application filed December 10,1897. Serial No. 661,408. (No model.)

To all whom it may concern:

Be it known that 1, HORACE S. BREEDEN, a citizen of the United States, residing at Min neapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Duplex Pen, of which the following is a specification.

This invention relates to duplex pens, its object being to provide an attachment to fit on an ordinary pen holder or handle and carry an additional pen, said' pen being slidably mounted and adapted to be projected in advance of the pen secured in the holder or retracted to the rear thereof, as desired.

The invention further contemplates a fountain attachment for the supplemental pen adjustably supported to adapt it for pens of different lengths.

lVith these objects in view the invention consists of the several details of construction and combinations of parts, as will be hereinafter fully described, and particularly point: ed out in the claims.

In the drawings, Figure 1 is a perspective view of an ordinary penholder and pen provided with my improved attachment, the supplemental pen being projected into position for use. Fig. 2 is a side elevation showing the supplemental pen retracted. Fig. 3 is a section on the line 00 0c of Fig. 2. Fig. 4 is a group showing the several parts of the attachment separated. Fig. 5 is an end view of the holder for the supplemental pen and fountain attachment.

Similar reference-mun erals indicate similar parts in the several figures.

1 indicates an ordinary penholder, and 2 the pen supported in the holder in the ordinary manner.

3 indicates a longitudinally-split sleeve formed of any suitable sheet spring metal, and 4. is a strip of metal curved transversely to correspond to the curvature of the sleeve and-supported thereon. Tongues 5 are struck up from the sleeve and extend through slots 6 in the plate and are folded down over upon the plate in order to secure the sleeve and plate together. The plate may, however, be secured to the sleeve in any other preferred manner. The edges of the strip 4 are bent upwardly and inwardly over the main portion to form guides 7, in which a transverselycurved plate 8 is mounted to slide upon the strip l. The plate 8 is provided with a series of perforations (indicated by 9) for a purpose to be hereinafter referred to.

10 indicates the supplemental pen, 11 the fountain attachment, and 12 the holder for the supplemental pen and fountain attachment. This holder is formed from a piece of sheet metal curved transversely and having its side portions bent inwardly toward each other to lie parallel with the curved central portion to form the curved recess 13, which forms a seat for the supplemental pen 10. The side portions are then given a return bend and secured at their edges to the outer face of the plate 8, and another curved recess 14: is thus formed, which serves as a seat for the butt-end of the fountain attachment 11, the plate 8 forming the lower wall of this recess. The recesses 13 and let are open at their rear ends, and consequently either the supplemental pen or the fountain attachment may be, if necessary, extended through the rear open end, and in this manner the supplemental pen and fountain attachment may be adjusted relatively to each other to get the best results, and a long pen may be used with a short fountain attachment, or vice versa.

Pens provided with my attachment are designed especially to use different-colored inks-that is, the ordinary pen-point can be used for writing with ink of one color and the supplemental pen for writing with ink of another -colorand my attachment will be especially useful for bookkeepers. In practice the sleeve 3 will be fitted on the end of the holder. immediately in rear of the pen and the plate 8 fitted in the guides 7, and when the pen 2 is being used the supplemental pen will beretracted in the position shown in Fig. 2. When, however, it is desired to use the supplemental pen, the writer can, by engag-.

finger and the plate and will prevent the finger from slipping on the plate.

By having the curved recesses in the holder 12 open at both ends it is obvious that the fountain attachment can be adjusted for use with either a long or short supplemental pen, and in this manner the attachment is capable of use regardless of the particular form of pen employed in the holder 12.

In my invention the split sleeve is of elastic metal to firmly clasp or grip the ordinarypenholder to hold itself firmly in place on the holder, and this elastic sleeve is provided with longitudinal guideways in which is fitted a slidable plate that carries the auxiliary pen 10. This carrier-plate is movable in the guideway of the fixed pen to have endwise movement thereon a sufficient distance to project the auxiliary pen beyond the ordinary pen, and this movement of the carrierplate and the auxiliary pen is directed by the guideways on the sleeve to make the auxiL iary pen occupy axial relation to the penstaff and not obliquely thereto, so that the auxiliary pen may be used with the same facility and advantage as the ordinary pen.

It will be understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim is- 1. In a duplex pen, the combination with an ordinary penholder and pen, of a sleeve mounted on the holder in rear of the pen and having guideways, a plate slidably supported on the sleeve in said guideways, a holder secured to the plate at its other end, and a supplemental pen supported in said holder, substantially as described.

2. 111 a duplex pen, the combination with an ordinary penholder and pen, of a sleeve mounted on the holder in rear of the pen and having guideways, a plate slidable on the sleeve in said guideways and provided with a series of perforations, and a supplemental pen carried by the plate at its front end, substantially as described.

3. In a duplex pen, the combination with an ordinary penholder and pen, of a sleeve mounted on the holder in rear of the pen and having guideways, a plate slidably supported on the sleeve Hin said guideways, a holder secured to the plate at its front end and provided with two recesses extending longitudinally thereof, and a supplemental pen and a fountain attachment supported in the respective recesses, substantially as described.

4. In a duplex pen, the combination with an ordinary penholder and pen, of a sleeve mounted on the holder in rear of the pen and having guideways, a plate slidably supported on the sleeve in said guideways, a holder secured to the plate at its front end and provided with two curved recesses extending longitudinally thereof and open at both ends, and a supplemental pen and a fountain attachment adj ustably supported in the respective recesses, substantially as described.

5. The combination with a pen-staff having a main writing-pen, of a guide-sleeve clamped firmly to said staff and provided with a longitudinal guideway, a slidable plate provided at its front end with a duplex holder and fitted to the gnideway for endwise adjustment on said sleeve, an auxiliary pen fitted to said holder for adjustment with the slidable plate and adapted to be projected thereby beyond the main pen, and a fountain attachment also clamped in said holder independently of the auxiliary pen and maintained by the holder in operative relation at all times to the auxiliary pen, substantially as described.

(3. In a duplex pen, the combination with an ordinarystaff and a pen, of a carrier-plate slidably fitted to said staff, and asupplemental pen and fountain attachment separately fitted to the carrier-plate for movement therewith and adjustable independently of each other in said carrier-plate, substantially as described.

7. In a duplex pen, the combination with a staff and a pen, of a carrier-plate slidably mounted 011 said stall and provided with a double holder, a supplemental pen fitted to said holder, and a fountain attachment adjustably attached to the holder and arranged beneath the supplemental pen, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

HORACE S. BREEDEN.
